SPECIFICATION forming` part f Letters Patent NO. 736,062, dated. August 1 1, 1903.

Application filed February 25, 1902. Serial No. 95,590. (No modelJ To all whom it may concern:

Beit known that I, JOHN S. C. BONHAM, miner, a citizen ofthe Commonwealth of Australia, residing at 79 Rowena Parade, Richmond,nearMelbourne,in the State of Victoria, Commonwealth of Australia, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention has been devised for the purpose of providing a pump which will be thoroughly efficient and can be driven with less expenditure of labor or driving power than the pumps of ordinary construction, while being more particularly applicable for alluvial or other mining purposes, seeing that it can be worked as a force-pump from the bottom or other part'of the shaft, thus effecting a saving of time which would otherwise be lost by the miner having to ascend or descend the shaft as the water gained on him. Provision is made for the attachment of a length of hose to the suction-pipe, thereby enabling the pump to be used in underlay or other crooked shafts.

In order that my invention may be clearly understood, Il will describe it by reference to the accompanying drawings, in which l Figure l is a vertical central section of my improved pump. Figs. 2 and 3 are horizontal sections on the respective lines 2 2 and 3 3 of Fig. l. Fig. 4.- is a side elevation of the upper portion or delivery-pipe of the pump, illustrating the lever used for operating it, while Fig. 5 is a transverse section online 5'5, Fig. 4; and Fig. 6 is a vcentral section of part of the delivery-pipe, illustrating a modification in the arrangement thereof.

The same letters of reference indicate Athe same or corresponding parts in all the figures.`

The barrel a of the pump may be secured to a wall, post, or other suitable support by lugs a', cast upon or otherwise attachedto it, or the bottom flange a2 of said barrel may be extended laterally and be provided with boltholes to facilitate its being securely fixed in position. The upper end of the barrel is tapered, as illustrated at o3, and forms a guide for the combined hollow piston-rod and delivery-pipe Z7, while the upper end c of the suction-pipe is secured to the bottom flange a2 ofthe pump-barrel co by bolts c', a leather or other washer c2 being inserted to maintain a perfectly-tight joint. The lower part or extension c3 of the suction-pipe is secured to the upper portion c by means of a screwed coupling o4, with leather or other packingrings c5 to make the joint, and this extension is notched, as illustrated at c6, so that a length of liexible rubber or other hose can be secured to it.

The combined hollow piston-rod and delivery-pipe b is screwed into a hollow plunger d, fitting withinthe barrel of the pump and provided with hydraulic packing or cupleather d to maintain a tight joint on its downward stroke. Alength of ordinary iron water-pipe b', Fig. 4, with screw connections, eX- tends from the upper end of the hollow combined piston-rod and deliverypipe b and can be carried up to any height to which the power available can force the water, the upper end ofsuch water-pipe being bent over, as illustrated in said Fig. 4, to form a convenient discharge.

If preferred, in case the combined hollow piston-rod and delivery-pipe b is of such a length as to become unwieldy its upper end may be arranged to slide within a sleeve or cylinder b2, connectedr by a reducing-socket b3 with the discharge-pipe b', a union bwith packing-rings b5, being provided upon the lower end of this larger pipe to maintain a water-tight joint, and yet allow the combined piston-rod and discharge-pipe -to `reciprocate freely therein. The plunger d, attached to the lower end of this latter, is fitted with a central bolt or set-screw d2, projecting downwardly from a bridge -piece d3, extending across the inside of said plunger, said bolt serving to clampa pair of concentric rings d4 d5, a packing-ring d6, andthe hydraulic packing or cup-leather d in position, and upon the upper end of this bolt is loosely mounted an uptake-valve e, (having leather or other packing e,) which allows the water to pass freely upward to the delivery-pipe b when the plunger d is forced down, while a Hap-leather `or other valve f in the lower end of the barrel a acts as la non-return valve on the upper end c of the suction-pipe.

The combined hollow piston-rod and delivery-pipe b may be operated by means of ale- IOO ver g, Figs. 4 and 5, fulcrumed upon a bracket or arm g', attached by clamps or clips g2 to the pump-barrel a or other suitable support, said lever being bifurcated where it passes around said piston or Where it is mounted upon its supporting arm or bracket and said lever being arranged to bear against antifriction-rollers h, projecting from clips or clamps h', secured to said rod b.

A pump constructed as above described will obviously be capable of being operated by manual or mechanical power, and the parts may be disconnected and be readily replaced with new ones in the event of their becoming worn or damaged in anyway, and, moreover, the pump, while being specially adapted for use in mining operations, (mainly by reason of the ease with which the operating-lever can be shifted to any convenient position in the shaft,) is also adapted for domestic or any of the many other uses for which pumps are usually employed.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In a pump, the combination, with the barrel, of a hollow piston-rod and deliverypipe, a hollowr piston secured to the end of manca said rod, a ring carried by said piston having a passage through it, a cup-shaped packingring adapted to be held in place by said ring, a bolt for holding said ring in place, a valve slidable upon said bolt and adaptedi to close said passage, and avalve in the lower end of said barrel, substantially as described.

2. In a pump, the combination, with the barrel, of a hollow piston-rod and deliverypipe, a hollow piston secured to the end of said rod, rings on the lower end of said piston having openings through them, a cupshaped packingring adapted to be held in place by one of said rings, a bolt for holding allof said rings in place, a valve slidable upon said bolt and adapted to close the openings in said rings, avalve in the lowerendof said barrel, and mechanism for reciprocating said piston-rod, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN S. C. BONHAM.
